The Primary Weapons Systems PWS MK218 Mod 2 Rifle 18" 308 Win is a refined AR-10 style platform built around a proven long-stroke piston system. Its 18 inch stainless steel barrel, paired with the FRC compensator and integrated bore evacuator, is tuned for reliable performance with .308 Winchester and 7.62x51mm ammunition, especially when running suppressed. Ambidextrous controls, a free-float M-LOK handguard, Magpul SL stock, and PWS enhanced grip come together to provide a balanced, controllable rifle for demanding shooters.

This MK218 Mod 2 configuration offers a 20 round capacity and adjustable gas regulator, allowing you to tailor the rifle to different loads or suppressed use while maintaining smooth cycling and reduced recoil. Its matte black anodized finish and synthetic furniture keep weight manageable without sacrificing durability, making it well suited for range work, training, and medium-game hunting where accuracy and consistency matter. Primary Weapons Systems is known for thoughtful engineering and piston-driven innovation, and the MK218 Mod 2 reflects that reputation in every detail.
